Question

As part of your summer job asa design
engineer-assistant at a NASA contractor, your team has been
assigned to design a powersystem for orbiting satellites. Your team
hasdevised an orbiting “drop cable” system that creates an induced
EMF by moving a cable througha magnetic field. In a test, your team
dropsa 30.0 km-long cable from the space shuttle,orbiting at a
speed of 8.00 x 103 m/s. The magnitude of theearth’s magnetic field
at the shuttle’s location isabout 6.50 x 10-5 T.

a) Find the motional EMFinduced between
the ends of the cable. Assume, and state, what the angle should be
between the cableand the magnetic field to get the largestEMF. b)
If you were to use this EMF (voltage)to operate electrical devices
on the satellite, you would haveto connect the far end of the wire
to thesatellite. Can you think how to do this? Drawa diagram and
show how current would flow.
